This 12.08ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846632878 or 846632878. Listed at 9 retailers as of November 2, 2026, with prices from £3,023 to £13,805, a £10,781 spread on the same certified stone. With Clarity lists it at £13,805. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
